A Treecreeper was calling loudly in Robertson Park, Renfrew this lunchtime. I have heard more over the last month or so than I can ever remember. I wonder if the calls are coming from adults shepherding fledged broods. The pair of Mute Swans on the park pond have managed to raise eight cygnets to almost adult size. When the sun came out, the Buddleja bushes along the northern edge of the park attracted Peacock and Red Admiral butterflies, the two hoverflies Eristalis pertinax and Volucella pellucens and a single Common Carder Bee.
